Justification:
This species has been largely extirpated from Lake Karla, due to almost total draining of the lake, and from the Kefalobriso spring (the type-locality), near the village Chasambali due to water extraction. It is still present, and possibly stable, in less than five locations (one location being the interconnecting channels of Lake Karla) within the Pinios river catchment with an estimated area of occupancy (AOO) <20 km².
